Abstract: The invention relates to a thermoelectric module for thermoelectric current generation, in particular in an exhaust gas system of an internal combustion engine, with a base plate and a plurality of thermocouples each with two legs, the thermocouples being electrically connected in series and mounted on the base plate. The invention provides that the base plate consists of a metallic material. This enables a low-cost production, allows substantially larger formats and makes the thermoelectric module mechanically much less sensitive than a conventional base plate made of ceramic. Furthermore, the invention includes a corresponding production method.

Abstract: The invention relates to a resistor alloy (3) for an electrical resistor, in particular for a low-resistance current-measuring resistor, having a copper constituent, a manganese constituent and a nickel constituent. According to the invention, the manganese constituent has a mass fraction of 23% to 28%, while the nickel constituent has a mass fraction of 9% to 13%. The mass fractions of the alloy constituents are adjusted to one another in such a manner that, compared to copper, the resistor alloy (3) has a low thermal electromotive force at 20° C. of less than ±1??/K. The invention furthermore includes a component made from such a resistor alloy and a production method therefor.

Abstract: The invention relates to a connecting element (4, 5), in particular a screw (4) or a nut (5), for mechanically connecting components (1, 2), the connecting element (4, 5) consisting at least partially of a material with a mechanical tensile strength of at least 350 MPa. According to the invention, the material of the connecting element (4, 4?, 5, 8) has an electrical conductivity of at least 50% IACS. The invention also relates to a corresponding production method for a connecting element (4, 5) of this type.
